CLOCK STRIKING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 445,607, dated February3, 1891.

Application filed Ju y 14, 1890. Serial No. 358,680. (No model.)

To aZZ whom it may concern:

Be it known that I, ALMERON M. LANE, a citizen of the United States,residing at Meriden, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements in ClockStriking Trains, of which the following is a specification.

My invention relates to improvements in clock striking-trains; and thechief object of my improvement is to lessen the rattling or grindingnoise incident to the revolution of the fly or fan.

In the accompanying drawings, Figure 1 is a front elevation of myimproved clock striking-train, together with the bell and timepiece anda sectional view of the base orcase within which the striking-train isinclosed. Fig. 2 is a sectional plan of the same on the line a a: ofFig. 1, and Fig. is a detached vertical section of a portion of saidstrikingtrain on the line y '1 of Fig. 2.

My improvement is applicable to any of the ordinary striking clocks;butI haveillustrated the same as applied to a time-piece in accordancewith my patent, No. 403,275, dated May 14, 1889.

A A designate the plates of the frame for the striking-train, the samebeing connected by pillars or posts 4 in the ordinary manner. The trainand lock-work or wires are also of the ordinary construction, (with theexception hereinafter noted,) and therefore need not be specificallydescribed. The cam it every half hour operates the lever Z) to pressupon the arm of the warning-wire to release the striking-train, asdescribed in my aforesaid patent. I make the Wheel 5 on the shaft thatdrives the pinion 6 of the fly or fan shaft 9 smaller than in theordinary strikingtrain and the pinion 6 on the shaft 9 of the fan or fly8 larger than in the ordinary train, and instead of having them directlyengage each other they are connected by means of the idle orintermediate Wheel 7, loosely mounted on a stud 11 on one of themovementplates. I also set the shafts 9 and 10 farther apart thanheretofore and make the blades of the fan or fly 8 longer. The frame forthe striking-train is of the same shape and size as I have heretoforeemployed, and the train contains the same number of shafts, wheels, andpinions, with the addition of the idlewheel.

By my improvements 1 make the fly or fan with longer blades and reducethe number of revolutions thereof without increasing the size of theframe. By thus reducing the number of revolutions I avoid the rattlingor grinding noise incident to the ordinary striking-train, produce atrain that is more durable, and one that requires oiling less frequently. The improvement adds nothing to the cost of production, as asoft metal pressed pinion (5 is substituted for an expensive steelpinion, the saving thus effected fully if not more than compensating forthe cost of the idle-wheel. The train will run for striking as manyhours as the train heretofore employed, although I have decreased thenumber of revolutions of the fly or fan, so that it revolves onlytwenty-five times for every stroke of the hammer, while in asimilartrain Without my improvement the fan or fly revolves one hundredtimes for every stroke of the hammer.

I claim as my invention- A clock striking-train having an idle-wheel 7interposed between the pinion of the fly or fan shaft and the wheelwhich drives said pinion, substantially as described, and for thepurpose specified.
